I have been searching around the internet to compare battery prices, and I have been to Battlepack, DynamoElectric (indvidual cell only), Eflightpacks, and Diversity Model Aircraft and it seems to me that DMA has the highest price on their batteries and pack. Why is that?? I don't think DMA's zap pack are supperior to Battlepack's zap pack or their normal non zap pack are superior to Eflightpack's non zap pack. So why are they so much more expensive?

The battery packs that I sell are not zapped. They are just regular cells put into packs, simple as that.

Zapped cells does give you an edge in term of power. The cell will maintain voltage as long as possible before it runs out of juice but when it does run out of juice, the voltage will fall very rapidly.

Zapped cells are not necessary if your anticipated current draw is below 40 amp.

DMA solder the cells together into packs whereas my packs are spot welded.

Oops, I meant to compare DMA's non zapped pack with Eflightpack's non zapped pack. I made a typo in my original post; thanks for correcting me Tony. I will edit my original post to make it clear now. But can anybody tell me why DMA's pack cost more?? In case of the zap pack, they cost significantly more than what Battlepack sells them for since Battlepack will zap your cells for free.

DMA's battery packs are hand made and very nicely done. If you're after max performance, IMHO, end to end soldered packs are the way to go. Steve is a good guy and will respond to email, usually within 24 hours. Satisfied customer here...
